 * Hello,
 * I’m running WordPress 3.5.2 on PHP 5.4 on Dreamhost (this error also affected
   PHP 5.3 on Dreamhost). When I upgraded from 2.02 to 2.12, I started receiving
   the following warning messages:
 * Warning: include_once([PATH TO WORDPRESS]/wp-content/plugins/autochimp/plugins/
   ContentSidebar.php): failed to open stream: No such file or directory in [PATH
   TO WORDPRESS]/wp-content/plugins/autochimp/autochimp.php on line 103
 * Warning: include_once(): Failed opening ‘[PATH TO WORDPRESS]/wp-content/plugins/
   autochimp/plugins/ContentSidebar.php’ for inclusion (include_path=’.:/usr/local/
   lib/php:/usr/local/php5/lib/pear’) in [PATH TO WORDPRESS]/wp-content/plugins/
   autochimp/autochimp.php on line 103
 * I tried downgrading to AutoChimp 2.11 and receive the same message. Help! Thanks!

 * I figured it out. My theme (PageLines) has a class named ContentSidebar, so the
   AutoChimp class autoloader was looking for that class in the plugins folder. 
   I added the following to the if statement on line 102 in order to fix the issue:
   &&
   file_exists(plugin_dir_path( __FILE__ ) . ‘plugins/’ . $class . ‘.php’)

 * Nate,
    I have the same theme and am trying to fix that same issue. Where exactly
   am I adding that line? Line 102 of what file exactly?
